In economics, cargo or freight are goods or produce being conveyed â generally for commercial gain â by ship, boat, or aircraft, although the term is now often extended to cover all types of freight, including that carried by train, van, truck, or intermodal container.
What are 'Consumables'. Consumables are goods used by individuals and businesses that must be replaced regularly because they wear out or are used up. They can also be defined as the components of an end product used up or permanently altered in the process of manufacturing, such as semiconductor wafers and basic chemicals.
These welding rods are referred to as consumable electrodes. For TIG welding, the welding rods do not melt, so are called non-consumable electrodes. Within both of these groups, there are many different variations and types, which will be covered in more detail later. Welding rods are usually coated, although the materials that make up this coating can vary widely.
